Most of the 33 miners trapped underground for more than two months in northern Chile have been winched to the surface amid scenes of jubilation.

The men have been trapped underground since August 5, when a rockfall caused a tunnel to collapse. Lisa Mullins talks with the BBC's Gideon Long at the site of the rescue operation.
